Industrial RS232-RS485 Ethernet Converter

This RS232/RS485 to Ethernet converter is an industrial-grade device that enables bidirectional transparent data transmission between RS232/RS485 and Ethernet. It can also be configured via a web page.

Key Features

• • Equipped with a high-performance 32-bit ARM processor (M4 series) with a clock speed of up to 120 MHz, ensuring fast and reliable operation.
  • Supports 10/100Mbps Ethernet interface with Auto-MDI/MDIX, allowing for easy connection with standard Ethernet cables (cross-over or straight).
  • Features both RS232 and RS485 interfaces that can operate independently without affecting each other.
  • Configurable baud rate (600bps~230.4Kbps) and supports five parity control options: None, Odd, Even, Mark, Space.
  • Multiple indicators for monitoring communication and operation status.
  • Supports various operating modes: TCP Server, TCP Client, UDP Server, UDP Client, HTTPD Client (GET and POST supported).
  • Compatible with Modbus, making it suitable for industrial applications.
  • Websocket support enables bidirectional transparent data transfer directly through a web page.
  • Configuration can be done through a web page, AT commands, serial protocol, or network protocol, allowing for integration into custom software.
  • Supports custom heartbeat packets to ensure connection status and active sensor data reception.
  • Supports custom record packets, which are automatically passed as identifiers after the connection is established, allowing differentiation of different devices.
  • Supports custom web pages, enabling users to customize the module's configuration page.
  • Similar to the RFC2217 protocol, it can communicate with devices whose serial settings (baud rate, data bits, etc.) can change.
  • Features a KeepAlive mechanism to detect and automatically reconnect to disconnected connections.
  • Supports timeout restart (restarting without data) for long-term stable connections, with configurable restart time.
  • Supports DNS domain name resolution and configurable DNS server.
  • Supports DHCP for automatic IP assignment or static IP configuration.
  • Firmware can be upgraded over the network or through hardware.
  • Factory settings can be restored through software and/or hardware.
  • Comes with a customizable default MAC address.
  • Includes provided software: module configuration software, TCP/UDP test tool, VCOM virtual serial port software.
  • Sample code available for various platforms: host computer (socket), VB, C++, Delphi, Android, iOS, etc.
